అల్లుని మంచితనంబును – సుమతి

Alluni manci tanambunu
gollani sahitya vidya komali nijamun
bolluna dancina biyyamu
dellani kakulunu levu teliyara Sumati!

polluna=chaff.

Sumati, know that these things do not exist: good behavior of a son-in-law, literary scholarship of a shepherd, truth uttered by a woman, rice from pounding chaff, and white crows.
It is difficult to obtain rice from chaff, there are certainly no white crows. But the three other things mentioned in this verse are not completely true. Son-in-law may be good; some shepherds may acquire literary knowledge, and women are truthful. Son-in-law might be too demanding, shepherds might not be educated, and women may have reasons to resort to falsehood. But these things are changing fast with the spread of education and interaction among different people.
